A)dryness.
B)saltiness.
C)acidity.
D)toxicity.
E)All of the choices are correct.

Accepted Answer

All of the choices mentioned (dryness, saltiness, acidity, toxicity) play a role in the antimicrobial aspect of the skin. Dryness and saltiness create an environment that is inhospitable to many microbes, while acidity (due to the presence of lactic acid and fatty acids on the skin) can help inhibit the growth of certain bacteria. Additionally, the skin produces antimicrobial peptides and other toxic molecules that help destroy or inhibit the growth of bacteria and fungi.
